    Abstract: A system and method for adapting the clean filter correction map for a selective catalyst reduction filter SCRF of an exhaust gas aftertreatment system are provided. The system may be in fluid communication with an engine of a vehicle. The system may include a first pressure sensor and a second pressure. A differential pressure module is in communication with the first pressure sensor and the second pressure sensor and configured to generate a delta pressure signal corresponding to a pressure drop between the first pressure sensor and the second pressure sensor. The system may also include a controller configured to determine a number of completed regeneration events of the SCRF; compare the number of completed regeneration events to an evaluation element; and enable an adaptation module by executing one of a first control action, a second control action, and a third control action.

    Abstract: A method is disclosed for controlling a diesel engine equipped with a diesel particulate filter (DPF). The method includes detecting steady state operation of the engine generating a first flow rate of particulate matter (PM) directed into the DPF. The method also includes, during the steady state operation, triggering exhaust gas recirculation to the engine and thereby directing a second PM flow rate that is greater than the first flow rate into the DPF. The method additionally includes detecting a PM flow rate exiting the DPF in response to the second PM flow rate directed into the DPF. The method also includes comparing the detected PM flow rate exiting the DPF with a PM flow rate threshold. Furthermore, the method includes regulating injection of fuel to regenerate the DPF, if the detected PM flow rate exiting the DPF is greater than the PM flow rate threshold.

    Abstract: An exhaust treatment system configured to treat exhaust gas generated by an internal combustion engine includes a reductant delivery system that injects a reductant solution into an exhaust gas. A selective catalyst reduction (SCR) device reacts with the reductant solution to reduce NOx from the exhaust gas. A control module is in electrical communication with the SCR device and the reductant delivery system. The control module determines at least one of an injection status of the reduction delivery system and a performance of the SCR device. The control module further determines at least one debounce time for delaying diagnosis of a NOx sensor based on at least one of the injection status and the performance of the SCR device.

    Abstract: A particulate filter device monitoring system for an internal combustion engine includes a particulate accumulation register configured to store an amount of particulate in a particulate filter. The particulate accumulation register includes a particulate accumulation trigger zone having a power limiting mode trigger. A power limiting mode trigger module is configured to limit output power of the internal combustion engine when the amount of particulate accumulation reaches the power limiting mode trigger. A particulate accumulation model module includes a particulate accumulation model configured to calculate changes in particulate accumulation in the particulate accumulation register at a first sampling rate when particulate accumulation is outside the particulate accumulation trigger zone, and at a second sampling rate when particulate accumulation is within the particulate accumulation trigger zone.

    Abstract: An exhaust treatment system to treat exhaust gas includes a particulate filter and a pressure sensor. The particulate filter is configured to trap soot contained in exhaust gas. The pressure sensor is configured to output a pressure signal indicative of a pressure differential of the particulate filter. The exhaust treatment system further includes a soot mass module configured to determine a soot mass. The soot mass is indicative of an amount of soot stored in the particulate filter based on the pressure differential and a soot model stored in a memory device. The exhaust treatment system further includes a continuously regenerating trap (CRT) compensation module configured to generate a variable CRT threshold. The CRT compensation module selectively outputs a CRT compensation value that modifies the soot model based on comparison between the NOx flow rate and the soot mass-based variable CRT threshold.
